Pros & Cons _ O-Ring vs. Quad-Ring

Hi all,

I know this isn't IV related but there is just so many experts in different fields that I thought it would be beneficial to ask this question here.

1. What are the benefits of using a Quad-ring as opposed to a O-ring?

2. Why would one choose a Quad-Ring over a O-Ring?

Thanks!

The quad ring looks good in theory to provide 2 sealing faces but in practice for most applications the regular o-ring does just as well. O-rings are much more common and easier to get.

Hi Mario, Thanks for replying. It is appreciated!

So the quadring doesn't provide better pressure retention and/or sealing than a oring?

In what case would one choose a quadring over a oring?

I'd check with whatever supplier you normally use to check if you're using an optimal solution.

You can see from the sales literature above they can only come up with a very small application window where quad are better than o-rings.

I do agree if you are designing and wondering about the best solution check with your local hydraulics company.

Quad ring won't rotate in the grove. Reduce failure.

Lube in the grove.

Reduce friction.

Agreed! Thanks Mario, I will make contact with the supplier and ask about the use case.
